[0034] Further, the positioning plate 5 comprises a fixed block 51 fixedly installed on the inner side of the cutting shell 3, a push rod 52 is installed through the center of the fixed block 51, the push rod 52 is in sliding connection with the fixed block 51, a push part 53 is fixedly connected to one end of the push rod 52, a spring 54 is sleeved on the circumference of the push rod 52, one end of the spring 54 abuts against the push part 53, the other end of the spring 54 abuts against the fixed block 51, a positioning tube 55 is fixedly connected to the other end of the push rod 52, and a plurality of push columns 56 are fixedly installed on the side of the positioning tube 55 close to the cutting machine body 1.

[0035] Further, the cooling mechanism 6 comprises a piston cylinder 61 fixedly installed in the cutting shell 3, a piston column 62 is slidably installed in the piston cylinder 61, the piston column 62 is fixedly connected to the push rod 52 away from the piston cylinder 61, the outer side of the piston cylinder 61 is communicated with an air outlet pipe 63, the air outlet pipe 63 is installed with a first one-way valve 64, the outer side of the piston cylinder 61 is installed with a second one-way valve 65, and a plurality of air holes 7 are formed in the positioning tube 55. When the push rod 52 moves, the piston column 62 moves, when the piston column 62 moves downward, the air pressure is generated in the piston cylinder 61, the gas in the piston cylinder 61 enters the positioning tube 55 through the first one-way valve 64 on the air outlet pipe 63, and is finally sprayed out from the air holes 7 in the positioning tube 55 to the cutting part of the cutting knife 2, when the piston column 62 moves upward, the external air enters the piston cylinder 61 through the second one-way valve 65, and prepares for the next air discharge.

When the cutting knife 2 completes the cutting action of the rubber sheet from top to bottom, the cam 44 rotates and pushes the pushing part 53, and drives the pushing part 53 to move towards the rubber sheet, and the pushing rod 52 drives the pushing column 56 on the positioning pipe 55 to gradually abut against the rubber sheet, so as to realize the positioning and fixing of the rubber sheet. When the cutting knife 2 completes the cutting action of the rubber sheet and leaves the rubber sheet, the cam 44 continues to rotate, and the pushing part 53 abutting against the cam 44 gradually moves away from the rubber sheet under the elastic force of the spring 54. The pushing rod 52 on the pushing part 53 drives the pushing column 56 on the positioning pipe 55 to gradually move away from the rubber sheet, and the positioning of the rubber sheet is released. At the same time that the pushing rod 52 moves, the piston column 62 is driven to move synchronously with the pushing rod 52. When the piston column 62 moves upward from the bottom of the piston cylinder 61, the air outside the piston cylinder 61 moves into the piston cylinder 61 through the second one-way valve 65. When the piston column 62 moves from the top of the piston cylinder 61 to the bottom of the piston cylinder 61, the air in the piston cylinder 61 moves into the positioning pipe 55 through the first one-way valve 64, and finally is transported to the cutting part of the cutting knife 2 through the air vent on the positioning pipe 55, so as to cool the cutting part of the cutting knife 2.
